Subject: [PATCH v2] mips: dts: ralink: mt7621: add cell count properties to usb

Add default #address-cells and #size-cells properties to the
usb node, which should be suitable for hubs and devices without
explicitly declared interface nodes, as:

"#address-cells":
description: should be 1 for hub nodes with device nodes,
should be 2 for device nodes with interface nodes.
enum: [1, 2]

"#size-cells":
const: 0

-- Documentation/devicetree/bindings/usb/usb-device.yaml

This version of the patch places the properties according to
the order recommended by:

Documentation/devicetree/bindings/dts-coding-style.rst

Drop these three lines, this explanation would be after --- line as
information about the changes from v1.

Please keep the empty lines. It's easier to read. I don't see anything on
the Devicetree Sources (DTS) Coding Style that would restrict this.

The reason I removed them was due to the SoC DTSI example shown in [1]
lacking empty lines between properties, but then using them instead as
visual separation between properties and child nodes, or at least that's
how I understood it when I looked at it.

Personally, I prefer the look of the SoC DTSI example - but I don't mind
recreating the patch set with the empty lines between the properties
left
entact.

As there is a mix of property spacing and ordering styles in mt7621.dtsi
already - what is the consensus on what a node in this file should look
like?

I also don't mind following that pattern and cleaning up the whole dtsi
according to that if it'll save us all time and energy in future.

Justin

There's no precise spacing style I maintain here. I simply group together
properties that describe a single attribute, and separate those that
describe different attributes.

If you'd like to improve the ordering style of the MT7621 device tree
sources accordingly with
Documentation/devicetree/bindings/dts-coding-style.rst, I'd be happy to
review those patches.

I'll recreate v3 accordingly.

Thanks, I'll make an attempt at this sometime soon.
